An older-model car that has not been maintained well,once used to describe late 50s-early 70s cars with tailfins but now can also be applied to 80s cars.Rustbuckets typically belong to people who,though they often have the means to get a newer car,are holding onto the past with both hands(see Dead Elvis).The back of a rustbucket tends to drag the ground,the exhaust pipes belch black fog,the seats spill stuffing and the air conditioner seldom works.

"Get a load of that old rustbucket,it hansn't seen a fresh coat of paint since Nixon was Prez!"
